About Oracle Enterprise Manager 12c : The architecture of the OEM for Grid Control has three distinct components: – The collection agent (Oracle Management Agent or OMA) – The aggregation agent (Oracle Management Server or OMS) – The repository agent (Oracle Management Repository or OMR) The OMA runs on the target host and collects information about hardware, OS, and services that run on the target. The OMS runs can be on single-node or multiple-nodes. The OMS collects the information from the OMAs into the repository. It also acts as the user-interface — by generating web-pages for database administrators to view the status of systems and services. The OMR is an instance of Oracle database that stores the data collected by the OMS. A quick guide to step by step instructions on installation and challenges.
